I seem to remember reading somewhere that TRIM will never be available in raid mode? Maybe wrong, I can't remember where I read it, but in any case I think the G2 will run better in most applications as a single drive. I'm going to give a single G2 a shot to see how it compares to 2 x25E's in raid 0. My guess is it will be quicker for the vast majority of tasks, but I'll soon see.
